Abstract
A font storage system for use in a typesetter having an electronically controlled character imaging device. The storage system, which preferably includes a floppy disk, has digital information stored thereon defining each character to be typeset by at least two outlines on a normalized X-Y grid. The digital information defining each character includes (1) digital numbers defining the X and Y coordinates of the initial start points of the outline and (2) digital numbers defining a plurality of straight line vectors extending successively along the character outlines. Each vector has a first digital number representing the X coordinate and a second digital number representing the Y coordinate distance from one end of the vector to the other.
Claims5
A typesetter for the automatic generation of characters comprising a character imaging system for writing graphics quality characters of any design on a print medium;
- a font storage system having digital data stored thereon defining each character to be imaged;
- and an electronic computation and control system, connecting said font storage system with said character imaging system, for controlling said character imaging system in accordance with said digital data;
- said character imaging system including a flying spot scanning device for writing characters by means of a plurality of parallel scanning strokes of a scanning beam;
- and
- said computation and control system including:
- means for producing a beam deflection signal, determinative of the amount of deflection of said scanning beam in the direction of each stroke, said beam deflection signal causing successive strokes of said beam to start substantially at the intercept point on one side of a character and to terminate substantially at the intercept point on the opposite side of said character.
